Toyota Tundra Luggage Compartment Bulb Size

Additional Notes

• The Toyota Tundra uses the 921 bulb for its luggage compartment across all specified model years from 2000-2020, with the exception of 2014-2017, which are not present in the specifications.
• The 921 is classified as a T15 wedge-base bulb, meaning it uses a plastic wedge at its base rather than a metal contact pin or bayonet fitting, allowing it to be inserted directly into a socket without rotation.
• The 921 bulb operates at 12 volts and draws 16 watts, which are standard ratings for low-intensity interior lighting applications in passenger vehicles.
• The 921 bulb conforms to ANSI standards as recognized in both the United States and Canada, placing it within a regulated specification framework that defines its electrical and physical characteristics.
• The T15 designation refers to the bulb's tubular glass envelope, with the numeric portion indicating a width of 15 eighths of an inch, a sizing convention used across the ANSI bulb classification system.
• Because the 921 is an ANSI-standardized wedge bulb, it is interchangeable with other bulbs sharing the same T15 wedge base and compatible voltage ratings, provided the wattage remains within the socket's rated tolerance.
